# DeleteLaunchTemplateVersions
<a name="API_DeleteLaunchTemplateVersions"></a>

Deletes one or more versions of a launch template.

You can't delete the default version of a launch template; you must first assign a different version as the default. If the default version is the only version for the launch template, you must delete the entire launch template using [DeleteLaunchTemplate](API_DeleteLaunchTemplate.md).

You can delete up to 200 launch template versions in a single request. To delete more than 200 versions in a single request, use [DeleteLaunchTemplate](API_DeleteLaunchTemplate.md), which deletes the launch template and all of its versions.

For more information, see [Delete a launch template version](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/delete-launch-template.html#delete-launch-template-version) in the *Amazon EC2 User Guide*.
